Roofing tongs

F. N. STEVENS ROOFING TONGS Filed Aug. 9, 1927 jaw '1 so as to disengage squaredil zey portions 1 5 from the previously engaged openings 14 of the aforesaidgage pins 12 'andto bring such key portions into snug engagement withit-he squared openingsof the 'irnierfrrostgage pins 12. -ZX-t tl-i'is-ti i'ne the pin shafts-16 are rotated whercupo'n said innermostgage pins 12 will be swung to positionsat sub'stairtiall'yright angles to the pable of being produced through the usage of the aforesaid gage pins 21 and 12;the

pivotingof the jaws 1 and 2 being again repeated, during which the extended and free portions of the now operatively positioned and innermost gage pins 12 will pass through the slots 20 of the jaw 2.

1 In this connection, it will be noted that I the spring fingers 10 adjacent the various ways or pockets 9 of the gage pins 12' will serve as means for releasablyretaining each of said gage pins in their inoperative positions within said pockets, and furthermore, that when said pairs of gage pins 12 are moved to their operative positions they will likewise be releasablyretained in these latter'positions by spring-bearing-like engagement of the fingers 10 upon the flattened; portions of the extremities of the shouldered portions or heads 13, hence insuring the positioning of the free extremities of the operated gage pins 12 so'that theywill freely engage in and pass through their respective slots 19 and 20 in the jaw 2.

Obviously the rotatable and transversely slidable pin shafts 16 afford means whereby said gage pins 12 may be independently and selectively operated, and at the same time will not interfere in any manner whatsoever with the normal mode of usage of the tongs.

Manifestly the construction shown is capable of considerable modification, and such modification as is within the spirit of my claims I consider within the scope of my invention.

I claim:

1. In combination with tongs of the character described, pairs of correspondingly positioned gage'pins mounted on one of the jaws thereof, means for operating each palr of pins whereby said pins may be selectively moved to positions at substantially right angles to the jaws, the remaining jaw having ways therein for receiving the free portions of the pins, when in operative positions, therethrough.

2. In combination with tongs of the character described, gage .pins mounted'on one of the jaws thereof, means to permit of selective engagement with each pin whereby said pins may be independently operated to positions at substantially right angles to the jaws, the l emai ningj aw having waysv therein for reeeivingilthe free portions of said pins therethrough when in operative positionsi In combination with tongs: of-the charae'ter' de 'scrrbe ncljird i ngzmovably m-terc'onn'eote'd awe; ene- :of said j a'ws having; pairs j of transversely r'lis-po'sed and longitudinally extend-i j ways fornie'd' therein; gage: pins i-iornrally' received within a'nd' longitudlnall y of said ways, certain ofthe extremities of said gage I pins having cross-sectionally squared openings formed therein, pin shafts engaged inbearing openings in said first: mentioned jaw each having a cross-sectionally squared key portion thereon, said pin shafts being rotatable and transversely slidable with respect to the jaw receiving the same and adapted to have the cross-sectionally squared key portions thereof engaged in either of the squared openings in the ex: tremities of said gage pins whereby with rotation of said shafts to swing said gage pins to operative positions at substantially"- right angles to said jaw, and the remaining jaw having transverse ways therein for re ceiving the free portions of said pins when in operative posit-ions, therethrough.

4:. In combination with tongs of the character described including movably interconnected jaws, one of said jawshaving pairs of transversely alined and longitudinally extending pockets formed therein, gage pins normally received Within said pockets havingcross-sectionally squared openingsformed incertain of the extremities thereof, shaft pins passed through bearing openings in portions of said first-mentioned jaw and each thereof having cross-sectionally i squared key portions adapted to beselectively engaged in the cross-sectionally squared openings in the extremities of said gage pins, said pin shafts being rotatable and transversely slidable with respect to the jaw receiving the same whereby to permit of selective engagement of either of said pins of the pairs and the swinging of the same to operative positions at substantially right angles to said jaw, fixedly mounted gage pins on said first-mentioned jaw beyond said first- 4 mentionedgage pins, and the remaining jaw having transverse slots formed therein for receiving the free portions of said gage pins therethrough at times. i a c 5. Roofing tongs comprising in combination a pair of jaws, a plurality of gage members mounted upon one of said jaws, a. shaft journaled within one of said jaws, and means connecting said gage members to said shaft whereby they maybe selectively moved into and out of operative position.

r 6. Roofing tongs comprising in combination a jaw, gage members pivotally mounted withinsaid jaw, means for normally retaining said gage members m'inoperatlve position withln said jaw, and means for causing Q said gage members fobesel'etiv ely projected from said jaw,substantiallyv as and for the y purpose specifiedf; H
